Silicone masterbatch can improve the wear resistance of shoe soles.
It is mainly based on the following mechanisms:
1.Filling mechanism
The filler in silicone masterbatch can be filled into the sole material to form a particle structure with higher hardness. These particles can reduce the actual contact area between the sole and the ground, thereby dispersing and relieving the force generated by friction, effectively reducing wear. In addition, high hardness filler particles themselves also have certain wear resistance, which can further enhance the wear resistance of the sole.
2.Lubrication mechanism
The silicone monomer in silicone masterbatch can undergo chemical reactions with the substrate in the sole material, forming chemical bonds or oxide compounds. These compounds form a lubricating film on the surface of the material, which can significantly reduce the friction coefficient between the sole and the ground. The improvement of lubricity helps to reduce the heat and wear caused by friction, thereby extending the service life of the sole.
3.Reaction mechanism
Other chemical reactions, such as crosslinking reactions, may occur between the silicone monomer in the silicone masterbatch and the substrate. These reactions can enhance the internal structure of the sole material, improving its overall strength and stability. A more robust and stable sole structure can better resist external wear, thereby enhancing wear resistance.
4.Improvement of processability and surface properties
The addition of silicone masterbatch can also improve the processability and surface properties of shoe sole materials. It can improve the flowability of thermoplastic resin in the molten state, making it easier to shape and shape the sole material during the processing. At the same time, silicone masterbatch can also improve the dispersion of fillers, reduce energy consumption in extrusion injection molding, and improve production efficiency. All of these contribute to producing more uniform and dense sole materials, thereby improving their wear resistance.
silicone masterbatch can significantly enhance the wear resistance of shoe soles through various mechanisms such as filling, lubrication, reaction, and improvement of processability and surface properties. In practical applications, the addition amount of silicone masterbatch is usually about 5%, which can achieve significant modification effects. Therefore, silicone masterbatch has broad application prospects and important application value in the field of shoe sole materials
